Operating with a wavelength of 980nm/810nm in the near infra-red portion of the spectrum, VELAS™ provides good haemostasis effect and bloodless operating due to high absorption in water and haemoglobin.Compared to the Nd:YAG laser, the thermal penetration is less deep enabling safe and precise proceduresare closed to delicate structures while protecting the surrounding tissue.Compared to the CO2-laser, this special wavelength provides a better significant haemostasis is allowing a bloodless operating field., even in highly vascular areas such as nasal polyps and haemangioma.
